Modelling particle non-sphericity at different levels for DEM and CFD-DEM simulations

Modelling particle non-sphericity at different levels for DEM and CFD-DEM simulations

The Project title is Modelling particle non-sphericity at different levels for DEM and CFD-DEM simulations. We use consider non-spherical particles in terms of super-quadrics as they demonstrate an excellent trade-off between shape flexibility and computational efficiency. 

The main aims of the project are the following. First, implementation of super-quadric contact detection methods in simple prototype python code that is already finished, and implementation of a chosen computationally efficient contact detection method and contact force law in open-source C++ LIGGGHTS DEM code that has just begun and later implementation of rolling friction models (secondment to UE). Comparison with (multi-)spherical approach. 

Second, developing and implementation of computationally efficient volume fraction calculation method as well as super-quadric drag force law for gas-solid flows in open-source C++ CFDEM-Coupling code, comparison of non-spherical and spherical drag laws. 

Third, develop a coarse-graining methodology to allow the application of DEM and CFD-DEM models to large-scale processes. 

Fourth, conduct calibration and validation experiments of single phase and gas-solid experiments for a variety of non-spherical particles. Solving of important industrial problems.
